Endurance Fuel for Running, Cycling, and High-Performance Training (900g)
Carbs. Salt. Real Montmorency tart cherry. Mixed in a bottle, taken on the move.
FTP Power Fluids Tart Cherry is a carbohydrate and electrolyte drink mix for endurance athletes — built to sit alongside our energy pastilles so you can hit 60–90g of carbohydrate an hour without eating all of it.
⚡ Pair it with pastilles: the full System for £49.99
This 900g bag + 1kg Energy Pastilles in your flavour + a free Adventure Pouch, 710ml bottle and pastille taster. Worth up to £91, £49.99 for your first box when you subscribe, then £59.99 per reload. Swap flavours, skip or cancel anytime. See the offer →
Tart Cherry or Core? Both work. Here's the difference
We make two Power Fluids at the same price, with the same 27g of carbohydrate per serving. The fuel is identical. You are choosing flavour, and whether you want caffeine in the bottle.
Tart Cherry — no caffeine, real Montmorency cherry.
Core (Neutral Citrus) — 50mg of caffeine per scoop, less than half a mug of filter coffee, and a neutral flavour that holds up over four hours.
Plenty of people keep both in the cupboard and pick by session. Neither is a mistake.

What Is Actually In The Bottle
27g of carbohydrate per 30g scoop, from dextrose and cane sugar — so you are taking on both glucose and fructose rather than glucose alone.
300mg of sodium per serving. Sweat losses vary enormously between athletes; 300mg per 500–750ml sits in the middle of the usual range for a moderate sweater.
3g of dried Montmorency tart cherry. Real fruit, not flavouring. It is why this one tastes the way it does.
No miracle powders — just fuel.
How to Use
Mix one 30g scoop with 500–750 ml of water. Drink during the session.
Typical carbohydrate intake targets:
• 30–60 g an hour for moderate efforts
• 60–90 g an hour for longer or harder sessions
One bottle of Power Fluids gets you to roughly 27g. Two pastilles get you another 30g. That combination is how most people reach the top of that range without a stomach full of liquid.
Practise your fuelling in training so race day is a repeat, not an experiment.

Questions
Before you order
Can't see your question? Message us and a real athlete on the team will answer.
Is Power Fluids a good Tailwind alternative?
Yes. Like Tailwind Endurance Fuel, Power Fluids is an all-in-one carbohydrate and electrolyte drink mix, so one bottle covers carbs and sodium together. Each 30g scoop gives 27g of carbohydrate from glucose and fructose plus 300mg of sodium, and a 900g pouch of 30 servings is £25.99, stocked and shipped from the UK. How to switch from Tailwind.
How much Power Fluids should I drink per hour?
Mix one 30g scoop with 500–750ml of water and drink it over about an hour. That is 27g of carbohydrate and 300mg of sodium. For 60–90g of carbs an hour, add 2 to 4 FTP Energy Pastilles alongside the bottle.
How much sodium is in Power Fluids?
300mg of sodium per serving, with potassium, calcium and magnesium. That suits most moderate sweaters. If you sweat heavily or it is hot, add an FTP Electrolyte Tablet to a second bottle rather than making your drink stronger.
Tart Cherry or Core: which should I choose?
Both have the same 27g of carbs and 300mg of sodium per scoop. Tart Cherry is caffeine free and made with 3g of real Montmorency tart cherry per serving. Core is a neutral citrus with a light 50mg of caffeine for key sessions and race day. Many athletes rotate the two.
Can I use Power Fluids with energy chews?
Yes, that is how it is designed. Fluids in the bottle, pastilles in the pocket: one bottle of Power Fluids plus 2 to 4 pastilles an hour gets most runners and cyclists to 60–90g of carbohydrate without relying on gels.
How fast is delivery?
We usually dispatch the same day if you order by 8pm UK time. UK mainland delivery is free on orders over £30, and most orders arrive 2 to 3 working days after dispatch.

Add to cartCustomers praised this carbohydrate and electrolyte drink mix for its "great taste" and easy mixing. Most found it "easy on the stomach" and effective for long runs and cycling. The tart cherry flavor is "refreshing without being too sweet," though some customers noted it can be overly sweet if not diluted enough.

great product. love it for a long run
R
Best product I’ve used, both for in-ride fuelling and staying upright afterwards!
J
I’ve been using the FTP gummy’s for the past few months and now I’d hit the bottom of my liquid carbs bag I thought I’d try FTPs tart cherry. Well just like the gummy’s I’m a full convert now. The flavour is the best I’ve had in a mixer. It’s light on the tummy and despite being lower carbs that what I’d been mixing previously, it gave me the energy I needed. I can’t see myself drifting from FTP now. I’ve only been doing 40 mile stints on the bike unlike the heights of summer. But I’m only using 1 scoop and one bottle with a couple of gummy’s for this stint. Overall flavour 10/10, carb level 8/10 (I could mix it stronger), but given I felt I had plenty of energy in the tank and fresh 30+ miles in I can’t see me needing to go any stronger.
M
This product is brilliant. Kept me going both through and after a recent HM. Tastes great, no lumps and mixes fab.
M
Used the starter pack today on the Cumbrian cracker today for the first time
Had no fueling issues and the taste was great
S
Best sports nutrition I’ve tried in 25 years of running! Great taste, easy to digest and fuels long runs and races perfectly.
G
Great taste, I use it half strength as I get dehydrated easily. Highly recommended ✅
A
Never had a carb powder before only ever used electrolytes and it was great to try both the citrus and cherry and the cherry will be great for after race recovery.
J
very strong and sickly. not a fan sorry. Love the chew's though!
A
First time trying carbs powder and it was fantastic really helped with fuelling long run
D
Great product. Tasted great and kept me going on my long ride.
M
I tried the starter pack and have already placed an order for more. The flavour is fantastic, easy on the stomach, and is such an easy way to get carbs and electrolytes together.
A
What a great product. Great refreshing taste and easy to digest. My new go to for long days in the saddle. Tart Cherry is also 10/10
R
Great product does just what it’s supposed to , mixes easily and tastes great. Superb
A
Wow this product is amazing. Shame it wasn't available 25 years ago when i was racing. great taste and works as it should
F
It tastes amazing! Not sure if there’s really enough cherry to aid recovery? But love it
D
I felt instantly refreshed after drinking the power fluid after a long run. I’m planning to take it with me on my next run.
S
Very happy with the mix, first time using something like this. Big fan of the flavour as it’s not too sweet, helped me through a hot 23km the other weekend.
J
Used it uesterday on a hot 70km ride and liked it a lot. Greta flavour, although I'd like it a little less sweet. Was easy on my stomach, no burps which was great compared to my previous drink. Went to order a subscription but out of stock. Any ideas on when you get a re up?
J
Amazing taste, the best flavour I’ve had. All of there products are great. Great find will continue to use.
G
Absolutely brilliant. Taste good and it’s such an easy way of getting your carbs when cycling or running.
J
Absolutely amazing product! I completed IRONMAN 70.3 Swansea and used your chews throughout the entire bike course. They kept my energy levels consistent from start to finish, and I came off the bike feeling energised and ready for the run. I couldn’t have asked for better nutrition on race day. Thank you for producing such a fantastic product!
R
Loving the product great taste
C
Very tasty and easy on the stomach. Fully recommend anyone to try it.
A
Very easy to eat and good on the stomach
N
I love the pastilles and don’t use gels anymore - this drink mix was just too sweet for me. I think my first bottle was too concentrated so would recommend using it more diluted if you don’t like sweet drinks.
M
As a recreational cyclist and general outdoors person I’ve been really impressed with this. The tart cherry flavour is refreshing without being too sweet, and it’s easy to drink on long rides or walks. Mixes well, sits nicely on the stomach, and gives steady energy without any crashes. Definitely one I keep coming back to.
C
Excellent item really taster a lots more user friendly than gels
J
The only drink mix I use now. Love that the bottle is dishwasher safe too.
M
Delicious and easy on the stomach. For me the combination of this with the chews is ideal.
Unlike most energy and electrolyte drinks, this has a brilliant flavour that isn't too overwhelming, great to take on a long run, I never get flavour fatigue with this.
